Applications in Testing: Drug Testing and Toxicity Screening: Organ-on-a-chip systems are used to test the effects of drugs, toxins, or environmental factors on specific organs. Researchers can study how these substances interact with cells in a more accurate representation of human physiology. Disease Modeling: These systems are employed to model diseases or disorders, such as cancer, diabetes, or other conditions. By replicating disease-specific conditions, researchers can study these diseases specifically.

Nanomedicine and molecular imaging are pivotal in advancing cancer diagnostics. Nanoparticles, at the molecular scale, can be engineered for targeted delivery of imaging agents or therapeutic payloads. In cancer detection, molecular imaging allows for the visualization of specific biomarkers or abnormalities at a molecular level, enhancing the precision of diagnosis. Nanomedicine's unique properties enable early detection by reaching inaccessible areas and delivering contrast agents for more accurate imaging. This integrated approach offers a sensitive and specific method for identifying cancer at its earliest stages. The synergy between nanomedicine and molecular imaging holds promise for improving diagnostic accuracy.

In the emerging DNA, RNA-based diagnostics, synthetic biology techniques create genetically modified DNA or RNA molecules that serve as probes to detect particular gene sequences in pathogens. These probes may be used for diagnostic purposes such as PCR Chain Reactions or CRISPR Diagnostics, enabling rapid and accurate identification of diseases. I found a new connection between cell-free systems and diagnostic kits. The development of cell-free systems containing essential cellular components that do not contain living cells is facilitated by synthetic biology. They can serve as diagnostic tools to diagnose diseases by simulating cellular functions in a monitored environment.

DNA computing, where DNA, RNA, and proteins are used to create computing systems that can perform complex calculations, potentially faster and more efficiently than traditional computers.
